Abstract : While traditional spectrometer, the portable spectrometer resolution is low, but because of its small body, light weight, Detection speed and ease of use, etc., which may in many widely used measurement and control, and other fields. Based on the understanding and comparison of different methods of analysis, based on combining fiber optics and solid-state image sensor technology development, A total based on the 1.30-path interferometer, and a multi-channel detector (CCD) space modulated Fourier Transform Spectrometer the conceptual design. This paper briefly describes the various spectrometer (dispersion-type, adjustable filter type, transform spectrometer) in the form, structure, Principle, and its performance is to give comments on this based on the concept of portable spectrometer design and the reasons for it. Then, according to the near-infrared (1064 nm) and on-site use of the specific requirements for the portable spectrometer of concrete case design, it has no mechanical scanning, Lumens, structural stability, easy to carry and faster detection of advantages, such as This is a portable Fourier Transform Spectrometer The working principle, as well as sub-systems, including front optical system, spectrophotometry system and the receiving system, signal processing system for an explanation and demonstration. Finally, the portable spectrometer parameters of the demonstration.
